CREATE SERVER ROLE (Transact-SQL)
Creates a new user-defined server role.
Server roles are server-level securables. After you create a server role, configure the server-level permissions of the role by using GRANT, DENY, and REVOKE. To add logins to or remove logins from a server role, use ALTER SERVER ROLE (Transact-SQL). To drop a server role, use DROP SERVER ROLE (Transact-SQL). For more information, see sys.server_principals (Transact-SQL).
Server roles cannot be granted permission on database-level securables. To create database roles, see CREATE ROLE (Transact-SQL).
Requires CREATE SERVER ROLE permission or membership in the sysadmin fixed server role.
Also requires IMPERSONATE on the server_principal for logins, ALTER permission for server roles used as the server_principal, or membership in a Windows group that is used as the server_principal.
This will fire the Audit Server Principal Management event with the object type set to server role and event type to add.
When you use the AUTHORIZATION option to assign server role ownership, the following permissions are also required:
To assign ownership of a server role to another login, requires IMPERSONATE permission on that login.
To assign ownership of a server role to another server role, requires membership in the recipient server role or ALTER permission on that server role.
A. Creating a server role that is owned by a login
The following example creates the server role buyers that is owned by login BenMiller.
USE master; CREATE SERVER ROLE buyers AUTHORIZATION BenMiller; GO
B. Creating a server role that is owned by a fixed server role
The following example creates the server role auditors that is owned the securityadmin fixed server role.
USE master; CREATE SERVER ROLE auditors AUTHORIZATION securityadmin; GO
